Augustine, feed on the scriptures, spit out all outside of it. Augustine (354-430): And I will lead them out from the nations, and gather them from the regions, and lead them into their own land, and feed them on the mountains of Israel (Ez 34:13). He established the mountains of Israel, the authors of the divine scriptures. Feed there, in order to feed without a qualm. Whatever you hear from that source, let that taste good to you; anything from outside, spit it out. In order not to go astray in the fog, listen to the voice of the shepherd. Gather yourselves to the mountains of holy scripture. There you will find your heart’s desire, there is nothing poisonous there, nothing unsuitable; they are the richest pastures. All you have to do is come to them in good health, in good health feed on the mountains of Israel. John E. Rotelle, O.S.A., ed., The Works of Saint Augustine, Part 3, Vol. 2, trans.

Latin text: Montes Israel, ubi pascua bona.---Et educam eas de gentibus, et colligam eas de regionibus; et inducam eas in terram earum, et pascam eas super montes Israel. Constituit montes Israel, auctores Scripturarum divinarum. Ibi pascite, ut securae pascatis. Quidquid inde audieritis, hoc vobis bene sapiat: quidquid extra est, respuite. Ne erretis in nebula, audite vocem pastoris: colligite vos ad montes Scripturae sanctae; ibi sunt deliciae cordis vestri, ibi nihil venenosum, nihil alienum; uberrima pascua est: vos tantum sanae venite, sanae pascimini in montibus Israel. De Pastoribus, Sermo XLVI, Caput XI, §24, PL 38:284.
